I often want the same files to be accessed by different apps on my Android phone, but the apps look in different folders. Is there a way to make two different folder paths on a FAT SD card point to the same file? For EXT, I think I could do this with a symbolic or hard link, but those don't exist for FAT. Can FAT be extended to support them? Can Android use an EXT-formatted SD card? Can a folder be mounted on top of another folder?

Works fine. Shows up in apps as if /sdcard/newdir has the same files as /sdcard/origdir, which is useful for sharing files between apps that look only in specific hardcoded folders. You should mention that you have to mkdir newdir first, though.

I'm not sure what more you want, clarified @endolith

My question is whether there's any way to produce a similar effect to symbolic links, considering that FAT doesn't support them. This isn't an answer, it's just a restatement of my question.

The answer would still be no. It isn't a restatement, it's my answer - atleast to my knowledge.
